Gantry (road sign)

The sign bridge (also signpost bridge or traffic signs bridge called short VZB ) is part of the street furniture and serves as a support system of groundbreaking signs or variable message signs. It is used mainly on motorways and multi-lane urban roads and allows them a secure routing.

A sign bridge consists of a latch / handle construction ( steel or aluminum hollow box, rarely also concrete), which is mounted on the side of the road foundations and are equipped as needed with a impact socket.

Next to the bridge variant also a one-sided lineup is ( boom or jib called ) is possible. In any case, a static calculation must prove the stability of the structure due to the large windage area.
